Ooo... I see bits different classes in you. Still, I'll go with black mage. YOur supportive but 'aggressive' nature, your calm and calculated but mindful ways, the type that can take the head charge if needed but would rather blast the enemy in hundreds from the rear guard.
I guess, you're more or less that black mage that doesn't really uses rods or staffs, but some sort of light weapon instead. 'Cause I get the impression that you would probably be the type that doesn't stay too much to the rear of the team, like some mages do.
